Razia: Contract ‘conflicts’ cause of Marussia test snub

Luiz Razia has confirmed that off-track “conflicts” caused him to sit out last week’s Barcelona test.

Despite intending to run its new Brazilian driver for two days in Spain, Marussia left Briton Max Chilton in the 2013 car for the entire test week, explaining only that it benefitted from the “consistency” of the amended schedule.
